摘要
上饶一陈家庙铜铀矿化带处于赣东北-浙西拗拉槽的CW端,矿化带内蚀变强烈,蚀变类型复杂多样,蚀变范围广。铜、铀矿化均受到蚀变带和流纹斑岩体的控制。控矿岩性为晚元古代早期大陆裂谷作用形成的巨厚火山-沉积建造。从成矿地质环境,矿化、蚀变特点看,上饶-陈家庙铜铀矿化带可与著名的奥林匹克坝Cu-U-Au矿床相类比。矿化类型又具有斑岩型矿床的特点。因而该矿化带具有良好的成矿远景和找矿前景。
Shangrao-Chenjiamiao Cu,U mineralized zone is on the Southwesten of Gandongbei- Zhexi aulacogen.A large scale of alteration in the zone are violent and complex.The mineralizations of Cu.U are controlled by the alteration and rhyolitephyres.The controlling deposits are volcanic-sedi- mentary formation formed by the continental rift during late-proterozoic.According to the features of mineralization,alteration and mineragenetic situation of geology,this mineralized zone can be correlat- ed to the famous Olympic Dam Cu-U-Au deposit.And more,the pattern of mineralization in the zone is of the characteristics of Phyre deposit.As a result,this mineralized zone is of broad mineragenetic prospect.
